Description

This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.

This versatile motor driver is intended for a wide range of users, from beginners who just want a plug-and-play motor control solution for their Arduinos (and are okay with a little soldering) to more advanced users who want a dual MC33926 carrier that requires fewer I/O pins to control. The Arduino pin mappings can all be customized if the defaults are not convenient, and the simplified MC33926 control lines are broken out along the left side of the board, providing a convenient interface point for other microcontroller boards (see the right connection diagram below). This versatility, along with an option to power the Arduino directly from the shield, sets this board apart from similar competing motor shields.

Properties
  • Wide operating voltage range: 5 – 28 V 1
  • Output current: 3 A continuous (5 A peak 2) per motor
  • Inputs compatible with both 5 V and 3.3 V systems
  • PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation
  • Current sense voltage output proportional to motor current (approx. 525 mV/A; only active while H-bridge is driving)
  • Motor indicator LEDs show what the outputs are doing even when no motor is connected
  • Can be used with an Arduino or Arduino clone (through shield headers) or other microcontroller boards (through 0.1″ header along the left side)
  • When used as a shield, the motor power supply can optionally be used to power the Arduino base as well
  • Arduino pin mappings can be customized if the default mappings are not convenient
  • Arduino library makes it easy to get started using this board as a motor driver shield
  • Detailed user’s guide
  • Reverse-voltage protection on motor supply 3
  • Robust drivers:
    • Transient operation up to 40 V
    • Over-current limiting via internal PWM
    • Over-temperature shutdown and hysteresis
    • Under-voltage shutdown
    • Output short-to-ground and short-to-Vcc protection
